Re: 14 mm spark plugs
I'm not sure whether the plug heat range makes a big difference depending on whether you are running an iron or aluminum head, but it might. Snyder's recommends using Champion RC12YC in their aluminum Model A head. From a previous discussion of this subject on the MTFCA forum, question posed by Mark Chaffin, the consensus of several post respondents was Bosch 4203. Three other mentioned were: Bosch 4501, Autolite 216, and Autolite 66.

Re: 14 mm spark plugs
Lang’s list 14mm spark plugs along with the 14mm plug adapters. They are Autolite plugs. They list them on their web site and catalogue.
